Linear algebra learning focused on plausible reasoning in engineering programs

Abstract

A methodological strategy is proposed for the teaching of Linear Algebra in engineering programs focused on plausible reasoning. These concepts were developed by [1] and [2], through the formulation and adaptation of interesting problems, whose design admitted a didactic model and a methodological procedure for the generation of conjectures through the mediation of technology and geometric visualization as key factors in the construction of the main concepts of the discipline by the students. The difficulties in the teaching and learning of Linear Algebra have been studied since last century, in particular since the nineties. The LACSG (Linear Algebra Curriculum Study Group) in the USA is a reference point. On the other hand, Anna Sierpinska and Jean-Luc Dorier lead another group in Canada and Europe. Both groups coincide that one of the greatest problems in the teaching and learning of Linear Algebra is the formal approach of the classes that are traditionally taught. The starting point of this study is the great difficulties students experience when assimilating definitions, theorems and demonstrations, which are elusive for the future engineers.
